The best way to get started is to start with a large fortune and turn it into a small one.

Any batteries that don't get used on a shoot here are always without fail discharged and then charged to a balanced storage level at the end of the day. They are too expensive to abuse. The older batteries that are laying about and used just for testing don't deliver the same performance that...

It is important to ensure that the surface of the prop is flat and not distorted as some of the Graupners are, also make sure you have a slight chamfer around the hole so that it does not raise the driving surface. It should then be possible to tighten the nyloc nuts without all of the brute...

I think there will be a lot of variations on the same principle but FWIW a tri copter has the most going for it. The FC with a 120deg. swash will do the job without too much brain work. The Naza-H has the tail rotor output built in that can control the rudder servo that tilts the rear rotor like...

Ken Well, it's a trade secret but my TDR's run at only 900 rpm. Due to the dev. done on blade design. The tips also disintegrate before too much impact damage. Starting up at 0 deg. would not work because your throttle needs to be at 50% at 0 deg. if you want to be able to autorotate or fly...

Well who said the rotor blades would be light or small, and Yuri we are talking about a single motor. The typical 720 size of blade that I use on the TDR (and most other modern blades) have lead cast into the leading edge of the blade getting heavier towards the tip. As far as mechanical drag...

Fortunately that was not mine. After the fix it never failed again, That is, once I had fixed it for the guy with DJI's help with the cost of parts. That is the same one that I used on the Shark commercial because it had been tested to death. Only with my own modified Zen. I had three in total...

Maybe the windings got damaged by fitting the motor with a screw that was too long...

I never had any problems with the S800 because I never used the bad GPS units. 250 trouble free flights, that is not to say that it is perfect by any means. The arms need to made stiffer and the prop.s need to changed.

The more one contemplates the better it sounds. Proper auto rotation and the possibility to use a standard Naza-H controller. A single central motor, almost stock tail rotor booms turned at 90 deg. with any number of available rotor sizes. It raises the bar in every aspect. Everytime your MR...

I have that problem with one of my MAC's It's your browser.

Why it's important for AP is the fact that the stabilisation is performed with a constant motor speed and a reliable mechanical servo response (like a heli) The engineering behind that is well developed and affordable. Throttle and pitch curve technology we already have. We only need a...

Sean If you have plenty of money we should talk. When it comes to learning how to become a pro shooter the fast and safe way.... I make peoples dreams come true.:tennis:

Looks like VP has finally arrived

Hi Where did you get that Pol. filter? Looks like it is doing the job OK.

Cool, I never saw that done before.

Still cant work out how you get pitch stab?

I think a tricopter would be even more efficient running 15" props. Something like a Turnigy Talon.

I think the first step in keeping civil UAV's out of trouble is to put a lower limit on the height that they can be operated around any built up area. Say 200 feet. AGL To venture above that height the operator should be qualified to at least the Private Pilots License standard (if you want to...

I have seen an issue with stability caused by moving a perfectly set-up S800 from Cyprus to Moscow the Declination is about 5 deg different and it seems to have caused a few problems as it was not reset. FWIW. We only use atti. mode for filming but it causes a compass error. Only three sets of...
